Detailed description of the invention
Below, embodiments of the present invention will be described in detail with reference to the accompanying drawings, and this embodiment, as an example, can be presented with multiple different shape by the people that field belonging to the present invention has a general knowledge, is not limited to the embodiment illustrated here.
Fig. 1 is the synoptic map being installed on the tyre inflater of vehicle according to one embodiment of the invention, Fig. 2 is the block diagram of the supply department that the tyre inflater being installed on vehicle of Fig. 1 possesses, and Fig. 3 is the block diagram of the control part that the tyre inflater being installed on vehicle of Fig. 1 possesses.
As illustrated in fig. 1, receive pressurized air in the compressor 200 of vehicle supply and the charging blower 300 being injected into the tire being installed on vehicle from possessing, comprising: charging blower port L6, flows into pressurized air from compressor 200; Control part 320, possesses according to pressure in charging blower port L6 and the pressure switch 321 of running; Supply department 310, is removably combined with charging blower port L6, to described tire injecting compressed air.
Control part 320 possesses ON/OFF switch 322, according to the running of pressure switch 321, to ECU (E) transmission signal.
Further, the feature of compressor 200 is, the air suspension 100 only possessed by vehicle supplies pressurized air, and the interior pressure of charging blower port L6 maintains more than higher limit.In other words, be equivalent to the state of the maximum pressure of general tire and more than the 3.03bar of 44psi, the state of air can be injected to tire, maintain the interior pressure of charging blower port L6.
In one embodiment of the invention, the interior pressure of charging blower port L6 be higher limit and below 3bar time, pressure switch 321 just entry into service.
Compressor 200 is formed: compressor reducer 210, for pressurized air; Suction passage L1, the side to compressor reducer 210 extends, and forms sucking hole 280, sucks extraneous air; Supply stream L2, supplies the air of compression to air suspension 100 and charging blower 300.
Suction passage L1 is equipped with filter 270, the dust existed in filtering external leaked-in air, supply stream L2 is equipped with boiler check valve 220, prevents pressurized air from driving in the wrong direction.
Supply stream L2 is divided into: suspension stream L3, is connected with air suspension 100; Charging blower stream L4, is connected with described charging blower 300; Reduce stream L5, be connected with described suction passage L1, excessive pressurized air discharged to outside.
The electromagnetic valve 110 that suspension stream L3 opens when possessing energising, injects air bellow 120 and operates for the air pressure that produces in open compressor 200, or is the air pressure of discharging air bellow 120 inside and operating.
Further, suspension stream L3 possesses air dryer 230, is fed to the pressurized air of air bellow 120 for drying; And flow regulating valve 240 is housed, contiguous air dryer 230, control the compressed-air actuated speed being fed to air bellow 120.
Reduce stream L5 and possess flow control valve 260; Pressurize for giving flow control valve 260 and from the control stream L7 that suspension stream L3 separates, possess Controlling solenoid valve 250.
The air pressure of air suspension 100 is excessive or when needing according to motoring condition adjustable pressure, compressor reducer 210 can stop, and Controlling solenoid valve 250 is energized and opens.
Further, pressurized air, by suspension stream L3, from air bellow 120 ramp metering stream L7, by the Controlling solenoid valve 250 opened, is pressurizeed to flow control valve 260.
Along with flow control valve 260 is pressurized and move, reduce stream L5 and suction passage L1 and be interconnected, by minimizing stream L5 and the suction passage L1 of connection, the pressurized air of air bellow 120 inside is discharged.
The one end of the charging blower port L6 that charging blower 300 possesses is combined with cock valve C, and compressor 200 and charging blower port L6 are interconnected.
Charging blower 300, comprising: charging blower port L6, flows into pressurized air from compressor 200; Control part 320, possesses according to pressure in charging blower port L6 and the pressure switch 321 of running, and according to the running of pressure switch 321 to the ON/OFF switch 322 of ECU (E) transmission signal; Supply department 310, is removably combined with charging blower port L6, to tire injecting compressed air.ON/OFF switch 322 is magnetic switch.
When the interior pressure of charging blower port L6 is below higher limit, pressure switch 321 makes ON/OFF switch 322 be communicated with ECU (E).At this moment, from the ECU (E) of ON/OFF switch 322 Received signal strength, compressor reducer 210 is made to operate and make to press liter in charging blower port L6.
Press when being raised to more than higher limit in charging blower port L6, pressure switch 321 becomes previous status, and along with pressure switch 321 becomes previous status, the signal that ECU (E) receives from ON/OFF switch 322 is isolated, and compressor reducer 210 can shut down.
Accordingly, the interior pressure of charging blower port L6 maintains more than higher limit, separates and press in the suspension stream L3 arranged side by side with charging blower port L6 also to maintain more than higher limit from supply stream L2.
According to control part 320, overall air pressure path can maintain certain interior pressure, without the need to the air pressure thesaurus of use storage air pressure and for measuring the pressure sensor of pressing in pneumatic circuit.
Supply department 310 possesses weather gauge 311, measures the compressed-air actuated size flowed into by charging blower port L6; Barrier valve 312, is communicated with or isolated tire and charging blower port L6.
The formation joint portion, side 314 of supply department 310, the joint portion 314 ' possessed with one end of charging blower port L6 combines.
